| 摘 要： | 在回顾叠前深度偏移发展历程的基础上,概述了当前几类叠前深度偏移方法:克希霍夫积分法、波动方程法、逆时偏移。在分析叠前深度偏移的波场成像方法、适用性、近地表条件敏感性及存在问题的基础上,对比偏移剖面,比较不同偏移方法的成像效果,指出叠前深度偏移的发展方向,为以后的叠前深度偏移的研究提供参考建议。 |
| 关 键 词： | 叠前深度偏移 克希霍夫积分法 波动方程 逆时偏移 近地表条件 |

| Abstract: | Based on reviewing the development of prestack depth migration,this paper has summed up several current prestack depth migration techniques,i.e.,Kirchhoff integration,wave equation,and reverse-time migration.On the basis of analyzing the prestack depth migration imaging method in such aspects as wavefield,applicability,sensitivity of the near-surface condition and existing problems,the authors made a comparative study of different migration imaging results by comparing the migration sections,indicated the d... |
| Keywords: | prestack depth migration kirchhoff integration wave equation reverse-time migration near-surface condition |
